Abstract

A switched-mode power supply system and method for converting an input voltage into an output voltage, including at least one switching stage controlled by a pulse-width modulation circuit in a clocked manner, and a control circuit that influences a pulse-width modulation circuit to vary the level of the output voltage, characterized by the provision of a current limiting circuit which, after a threshold voltage has been exceeded, limits the power supply output current first to an elevated maximum current for a first period of time, and thereafter to a regular maximum current. The control circuit is such that the first period of time for which the output current is limited to the elevated maximum current is dependent on the level of the output current.
